另一个!

let result const givenStr = 'A, X' //values separated by comma or space. const allowed = ['A', 'B'] const given = givenStr.split(/[\s,]+/).filter(v => v) console.log('given (array):', given) // given contains none or only allowed values: result = given.reduce((acc, val) => { return acc && allowed.includes(val) }, true) console.log('given contains none or only allowed values:', result) // given contains at least one allowed value: result = given.reduce((acc, val) => { return acc || allowed.includes(val) }, false) console.log('given contains at least one allowed value:', result)

不是最好的答案，也不是最干净的答案，但我认为它更宽容。 比如，如果你想对所有的支票使用相同的过滤器。 实际上.filter()与数组一起工作并返回一个过滤后的数组(我发现这也更容易使用)。

var str1 = 'hi, how do you do?';
var str2 = 'regular string';
var conditions = ["hello", "hi", "howdy"];

// Solve the problem
var res1 = [str1].filter(data => data.includes(conditions[0]) || data.includes(conditions[1]) || data.includes(conditions[2]));
var res2 = [str2].filter(data => data.includes(conditions[0]) || data.includes(conditions[1]) || data.includes(conditions[2]));

console.log(res1); // ["hi, how do you do?"]
console.log(res2); // []


// More useful in this case
var text = [str1, str2, "hello world"];

// Apply some filters on data
var res3 = text.filter(data => data.includes(conditions[0]) && data.includes(conditions[2]));
// You may use again the same filters for a different check
var res4 = text.filter(data => data.includes(conditions[0]) || data.includes(conditions[1]));

console.log(res3); // []
console.log(res4); // ["hi, how do you do?", "hello world"]

const givenArray = ['Hi, how are you'， 'how are you'， 'howdy, how you doing'] const includeValues = ["hello"， "hi"， "howdy"] const filteredStrArray = givenArray。filter(str => includeValues)str.toLowerCase().includes(value))) console.log (filteredStrArray);

你可以这样做

["hello", "hi", "howdy"].includes(str)

与数组数据/的精确匹配

const dataArray = ["amoos"， "rifat"， "hello"]; const findId = (data, id) => { 让res = data。Find (el => el == id) 返回res ?真:假; ｝ console.log(findId(dataArray， 'Hi')) // false console.log(findId(dataArray， 'amoos')) // true

这可以通过使用Array和RegEx的一些/每个方法来完成。

检查list(array)中的所有单词是否存在于字符串中:

const multiSearchAnd = (text, searchWords) => (
  searchWords.every((el) => {
    return text.match(new RegExp(el,"i"))
  })
)

multiSearchAnd("Chelsey Dietrich Engineer 2018-12-11 Hire", ["cle", "hire"]) //returns false
multiSearchAnd("Chelsey Dietrich Engineer 2018-12-11 Hire", ["che", "hire"]) //returns true

检查list(array)中的任何单词是否存在于字符串中:

const multiSearchOr = (text, searchWords) => (
  searchWords.some((el) => {
    return text.match(new RegExp(el,"i"))
  })
)

multiSearchOr("Chelsey Dietrich Engineer 2018-12-11 Hire", ["che", "hire"]) //returns true
multiSearchOr("Chelsey Dietrich Engineer 2018-12-11 Hire", ["aaa", "hire"]) //returns true
multiSearchOr("Chelsey Dietrich Engineer 2018-12-11 Hire", ["che", "zzzz"]) //returns true
multiSearchOr("Chelsey Dietrich Engineer 2018-12-11 Hire", ["aaa", "1111"]) //returns false
